Which microcontrollers do boards using the ATtiny25-20P use?

Most are built on AVR/Arduino (2).

How big is a typical board using the ATtiny25-20P?

The median is 40 × 60 mm, and 100% are two-layer designs.

What is the most popular open source board using the ATtiny25-20P?

By GitHub stars, Lichtschranke-M-jack by REcassy, with 1 stars.

Can I simulate one of these boards using the ATtiny25-20P before building it?

Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
