I'm not knowledgable of the amount of all the lokas, but i can give you scriptural reference that could aid you
Srimad Bhagavatam 2.5.36 to 2.5.38-2.5.41:
yasyehāvayavair lokān
kalpayanti manīṣiṇaḥ
kaṭy-ādibhir adhaḥ sapta
saptordhvaṁ jaghanādibhiḥ ||
(SB 2.5.36)
Great philosophers imagine that the complete planetary systems in the universe are displays of the different upper and lower limbs of the universal body of the Lord.
bhūrlokaḥ kalpitaḥ padbhyāṁ
bhuvarloko 'sya nābhitaḥ
hṛdā svarloka urasā
maharloko mahātmanaḥ ||
(SB 2.5.38)
The lower planetary systems, up to the limit of the earthly stratum, are said to be situated in His legs. The middle planetary systems, beginning from Bhuvarloka, are situated in His navel. And the still higher planetary systems such as Suvarloka and Maharloka, occupied by the demigods and highly cultured sages and saints, are situated in the chest of the Supreme Lord.
grīvāyāṁ janaloko 'sya
tapolokaḥ stana-dvayāt
mūrdhabhiḥ satyalokas tu
brahmalokaḥ sanātanaḥ ||
(SB 2.5.39)
From the forefront of the chest up to the neck of the universal form of the Lord are situated the planetary systems named Janaloka and Tapoloka, whereas Satyaloka, the topmost planetary system, is situated on the head of the form. The spiritual planets, however, are eternal.
tat-kaṭyāṁ cātalaṁ kḷptam
ūrubhyāṁ vitalaṁ vibhoḥ
jānubhyāṁ sutalaṁ śuddhaṁ
jaṅghābhyāṁ tu talātalam
mahātalaṁ tu gulphābhyāṁ
prapadābhyāṁ rasātalam
pātālaṁ pāda-talata
iti lokamayaḥ pumān ||
(SB 2.5.40-2.5.41)
Know from me that there are seven lower planetary systems out of the total fourteen. The first planetary system, known as Atala, is situated on the waist; the second, Vitala, is situated on the thighs; the third, Sutala, on the knees; the fourth, Talātala, on the shanks; the fifth, Mahātala, on the ankles; the sixth, Rasātala, on the upper portion of the feet; and the seventh, Pātāla, on the soles of the feet. Thus the infinite form of the Lord is full of all planetary systems.
