It's a floor pump. This one: https://www.action.com/fr-fr/p/2561081/pompe-a-velo/ I also have a hand pump but I guess it's not particularly useful right now?
This is my floor pump against a typical presta valve easily holding ~175psi. You should be able to get well over 100psi on any floor pump against a closed valve.
Take the bike/pump to a local bike shop to compare readings and pressures against a known good source or at least just take your pump(s) and verify against a known good pump.
There's no risk to using force? Maybe I just didn't push hard enough because I was scared to put too much pressure on the presta and bend it. They look weak.
No risk. Road can go well over 100 psi in road stuff all the time.
