Which IC can I use to control 7-segment display? I want to make simple projects like a reaction timer but I don't have an Arduino or some other microcontroller available. What ICs can I use instead?

Assuming you are talking about LED 7 segment displays (as opposed to LCDs), you could use the '47 or '247 devices from the 7400 logic family, e.g. 7447.
In addition to @fmunkert
If you're talking about 7-segment LCD, you could use CD4054/4055/4056 CMOS chips.
