- I am considering to set up a cyber cafe.
- I am considering setting up a cyber cafe.
I think it should be version #2 where the verb considering is followed by the gerund setting. But it sounds unnatural to me.
Can we use a gerund after "Verb+ing"?

Yes.
To native ears, the two consecutive gerunds don’t sound especially remarkable even though they both end with -ing. The construction is fairly common:
The contractor is delaying building the front porch.
We’re risking missing our plane.
I'm imagining writing a silly ending to this answer.
Three gerunds in a row is unusual but tolerable:
Some doctors are considering stopping recommending high-carbohydrate diets.
Four gerunds in a row sounds silly, though it’s still grammatically correct:
I’m enjoying imagining finishing writing this answer.
A Google search turns up 55,000 books that contain considering setting up.
Considering setting up is perfectly grammatical, but (as you correctly sense) pairing the participle with the identically-formed gerund runs up against the horror aequi principle: hearers and readers don't like immediately consecutive uses of the same construction in different roles.
(But it is entirely acceptable to repeat a construction in a parallel or deliberately contrasting roles.)
Unhappily, you can't substitute an infinitive for the gerund, because consider does not license infinitive complements. Your only recourse here is rewriting to eliminate the jangling terms, or at least separate them:
I'm thinking about setting up a cyber cafe.
I've been thinking I might set up a cyber cafe.
A notion I'm considering is setting up a cyber cafe.
You actually do not have two gerunds in a row in that case. "I am considering" is actually a present progressive tense of the verb "to consider." "Setting up a cyber cafe" is the direct object of that sentence, started off with the gerund form of "to set."
The present progressive is visible if you look at how the sentence would appear in other tenses, in particular the past tense:
"I considered setting up a cyber cafe."
I don't entirely understand why English requires the direct object clause to start with a gerund, but I think it might become more clear when the direct object is a one-word verb, rather than a full clause
"I am considering sitting."
"I considered sitting."
In these cases, it is clear that a gerund is needed so that "to sit" can function as a noun. This also shows why English speakers will not use an infinitive -- because it is not a noun so cannot function as a direct object:
"XX I am considering to sit. XX (improper)"
I think that all -ing words except "am enjoying" in Ben's "I’m enjoying imagining finishing writing this answer" are gerunds, each one acting as the direct object of the previous one. However, it may be as simple as "it sounds better to our ears, so we say it that way."
Anything with auxilliary be and then the 'ing' form is a present participle. So technically if you say I am considering running for presented its :PN+ aux Be+ present part+ gerund + etc....and not 2 gerunds in a row....
Yes, in fact "Keep continuing studying" is also acceptable. (Can anyone please confirm this?)
