Yes. Pull up bar / Chin up bar, same thing.

Yo is it better to get a barbell for squats and deadlifts or dumbbells will do?

either one would do. but its dreadfully expensive to add weights though, not to mention what it would do to your floor tiles if you decide to go heavy..
i calculated the weights for me to squat 1.5 x bodyweight and plates alone are 1k++ . Would much rather paying for gym fees than building my own gym set at home

actually dumbell is better compared to barbell.. barbell dont allow full range of motion that dumbell have.. and is more prone to injury. The problem with dumbell is that the weight is limited.. compound exercise like squats need to use heavy weight.

The only way to make yourself more prone to injury is to do the exercise wrongly, with too much weight.

How heavy must u squat?10KG not enough for beginner?

How heavy depends on the individual, if you can squat 10kg and feel the "burn" after doing X amount of reps with X amount of reps, and get good gains, then why not?

Ah I see,well first time I did it,I can indeed feel it working and the next day,it was a bit sore

But one thing I still dun get,squats is a compound exercise,it trains the a few legs muscles and the lower back,but I don't get how it can help in overall muscle gain?

Try not to use too much weight at one go. I would suggest you to start slowly and once your body have adjusted to the weight, then only you slowly add more weights to it. You do not want to strain your muscles too much till the point that you're not able to work out for the next few days right?

Yea of course
