Sat Sri Akal
Well, I don't think they are called Narakh or Swarg specifically, they are named after different kinds of hells, like rasthal (different patalas) for example.

Please let us take a look at the saloka of Kabir ji when it is seen along with some of its partner verses. This is from Ang 1377. I think we will attain a better understanding of what is meant by "hell" if we see it in context.
I have not done a careful check of the translation, so some of the verses may not be exact. However we are looking at Kabeer ji's vision that contrasts the hell of arrogance and ego with the constant bliss of the company of his beloved Friend.
ਕਬੀਰ ਭਾਂਗ ਮਾਛੁਲੀ ਸੁਰਾ ਪਾਨਿ ਜੋ ਜੋ ਪ੍ਰਾਨੀ ਖਾਂਹਿ ॥
Kabīr bẖāʼng mācẖẖulī surā pān jo jo parānī kẖāʼnhi.
Kabeer, those mortals who consume marijuana, fish and wine -
ਤੀਰਥ ਬਰਤ ਨੇਮ ਕੀਏ ਤੇ ਸਭੈ ਰਸਾਤਲਿ ਜਾਂਹਿ ॥੨੩੩॥
Ŧirath baraṯ nem kī▫e ṯe sabẖai rasāṯal jāʼnhi. ||233||
no matter what pilgrimages, fasts and rituals they follow, they will all go to hell. ||233||
ਨੀਚੇ ਲੋਇਨ ਕਰਿ ਰਹਉ ਲੇ ਸਾਜਨ ਘਟ ਮਾਹਿ ॥
Nīcẖe lo▫in kar raha▫o le sājan gẖat māhi.
Kabeer, I keep my eyes lowered, and enshrine my Friend within my heart.
ਸਭ ਰਸ ਖੇਲਉ ਪੀਅ ਸਉ ਕਿਸੀ ਲਖਾਵਉ ਨਾਹਿ ॥੨੩੪॥
Sabẖ ras kẖela▫o pī▫a sa▫o kisī lakẖāva▫o nāhi. ||234||
I enjoy all pleasures with my Beloved, but I do not let anyone else know. ||234||
ਆਠ ਜਾਮ ਚਉਸਠਿ ਘਰੀ ਤੁਅ ਨਿਰਖਤ ਰਹੈ ਜੀਉ ॥
Āṯẖ jām cẖa▫usaṯẖ gẖarī ṯu▫a nirkẖaṯ rahai jī▫o.
Twenty-four hours a day, every hour, my soul continues to look to You, O Lord.
ਨੀਚੇ ਲੋਇਨ ਕਿਉ ਕਰਉ ਸਭ ਘਟ ਦੇਖਉ ਪੀਉ ॥੨੩੫॥
Nīcẖe lo▫in ki▫o kara▫o sabẖ gẖat ḏekẖ▫a▫u pī▫o. ||235||
Why should I keep my eyes lowered? I see my Beloved in every heart. ||235||
ਸੁਨੁ ਸਖੀ ਪੀਅ ਮਹਿ ਜੀਉ ਬਸੈ ਜੀਅ ਮਹਿ ਬਸੈ ਕਿ ਪੀਉ ॥
Sun sakẖī pī▫a mėh jī▫o basai jī▫a mėh basai kė pī▫o.
Listen, O my companions: my soul dwells in my Beloved, and my Beloved dwells in my soul.
ਜੀਉ ਪੀਉ ਬੂਝਉ ਨਹੀ ਘਟ ਮਹਿ ਜੀਉ ਕਿ ਪੀਉ ॥੨੩੬॥
Jī▫o pī▫o būjẖa▫o nahī gẖat mėh jī▫o kė pī▫o. ||236||
I realize that there is no difference between my soul and my Beloved; I cannot tell whether my soul or my Beloved dwells in my heart. ||236||
ਕਬੀਰ ਬਾਮਨੁ ਗੁਰੂ ਹੈ ਜਗਤ ਕਾ ਭਗਤਨ ਕਾ ਗੁਰੁ ਨਾਹਿ ॥
Kabīr bāman gurū hai jagaṯ kā bẖagṯan kā gur nāhi.
Kabeer, the Brahmin may be the guru of the world, but he is not the Guru of the devotees.
ਅਰਝਿ ਉਰਝਿ ਕੈ ਪਚਿ ਮੂਆ ਚਾਰਉ ਬੇਦਹੁ ਮਾਹਿ ॥੨੩੭॥
Arajẖ urajẖ kai pacẖ mū▫ā cẖāra▫o beḏahu māhi. ||237||
He rots and dies in the perplexities of the four Vedas. ||237||
This is not about "hell" apart from a hellish existence on earth. The first two verses tell us that someone who makes a show of status through rich diet and drink, and who makes an egotistical show of their virtue and devotion though pilgrimages and the like, they do not go to hell, but rather they come into their inheritance. It is hell, their spiritual inheritance; they do not have to be dead to inherit the wages of their pride.
In contrast to coming into an inheritance from arrogance and ego, Kabeer ji says in the next two verses, "I already enjoy the pleasure of the company of my beloved. And I do not brag about it, I keep it to myself, I keep my counsel because I am not one to make a show of my devotion.
Then Kabeer ji says, I won't lower my eyes to make it look as if I am so pious and humble. I won't make a show of that. I cast my eyes instead into the face of my beloved whom I find everywhere in every heart.
Kabeer ji then says let us all rejoice when we find the beloved within. There is no difference, we are like lovers who live constantly in each other's gaze. Our beloved is within, and we are within the beloved. In other words acts of piety like pilgrimages are unnecessary. And no one has to be notified; the one who matters most already knows..
Finally Kabeer ji says, and there are more saloks, I am stopping here. Kabeer ji says, the Brahmin (reference to those who make outward shows of piety through pilgrimages, rituals and fasts) may be recognized as gurus to the world (which in the times of Kabeer ji, that is how they served, teachers and keepers of the vedas). However they have nothing of value to teach the true devotee (the one who has that friend who never forsakes us). What happens to that Brahmin? He also comes into his inheritance. He rots in a hell of his own making: his vedas are so complex and his teachings are so complicated! How can he teach anyone?
I will go back and polish up the translations later.
