Hello there,
I am from the USA and I do not know what guitars are available there, nor do I have any idea of what they cost there.
On the guitar. You can some with a fixed bridge and some with a tremolo bridge. Decide if you want a whammy bar. It is not practical to add a tremolo bridge to an inexpensive guitar. So narrow the choices down by whether you want a whammy bar. If you do want a whammy bar, that eliminates all those with a fixed bridge. If you do not want a whammy bar, that eliminates all those with a tremolo bridge.
For the most part, all the guitars you have listed are the low end quality wise of those brands. The Gio series by Ibanez are very cheap quality guitars. Same for the Squier Bullet. Most BC Rich are pretty low quality. Frankly, the Gregg Bennett may be the best quality guitar of that group. But decide about the whammy bar. Then test the remaining choices to see which feels most comfortable for you to play and which has the sound you like best. The feel of the neck and the shape and weight of the body are comfort matters and are personal preferences. What I find comfortable to play, you may not. So test those remaining choices go with the one that feels most comfortable for you to play. There is not a lot of difference quality wise in that group.
Amps. I don't know the Stranger amp. I have never played one, nor do I have any friends that play them. The Roland Cube is all right. It is not high on my list. For newer players, I would think that a 1x12 combo amp from Fender, Vox, Marshall, Crate, Peavey or Line 6 would be a good choice. Again, I don't know how available or expensive those brands are in India. But those are all good amps.
Whatever amp you do pick, make sure it has a 12 inch speaker (if it is a single speaker model). Do not go with a small practice amp that has a 6 inch or 8 inch speaker. Those make you sound thin and tinny. Also amps under 30 watts don't handle gain and distortion very well. They run out of head room. However, most 1x12 combos are at least 30 watts.
Pedals. Many of the amps have built in distortion. And it is all right, but not great. My problem with the built in distortion in those amps is the lack of adjustment to the effect. You really are too limited in how much you can dial in the exact tone you want. Even with the amps that have a built in distortion effect, I seldom use it. I prefer to go with a distortion pedal. A good basic distortion pedal that is fairly inexpensive (here in the US) is the Boss DS-1.

If you want a distortion pedal that is better for metal, but not as versatile as the DS-1, the Boss Metal Zone is a good choice.

For a wah wah pedal, the Crybaby is the best.
