How to connect several external components at once to a micro bit

Answer 1

See what pins your modules are using.
If different, then the problem is only how to physically connect them. For microbit, there are ready-made extension boards, where all the pins are brought out for convenient connection, but you can simply solder the wires to the comb.
If the modules share common pins (besides power), then things get more complicated. You need to look at exactly what interfaces are there, whether several devices can work on them in parallel, and whether they can be reassigned to other pins.
