PAT1220-C-10DB-T5 is a 10dB attenuator. (This chip is just an example, it could be any other component as well).
Can I simply connect 3 of them in series in a PCB design to make my cheap 30dB attenuator?
I have a few attenuator modules with an SMA connector. One of them is 20dB while others are 6dB and 10dB. Can I again connect them in series to get higher attenuation?

Be aware that as you get to >> 40 dB attention, leakage around the components will start to exceed the attenuated signal. You start to need to put each stage in a separate shielded can or cavity.

Yes, you can cascade attenuators to realize more attenuation. Attenuation (in dB) will increase algebraically, as long as all individual attenuators are designed to operate at the same impedance and they are operating at that impedance. For example, mixing 75$Omega$ and 50$Omega$ attenuators may produce unexpected results. Same for using terminators in a system that doesn't terminate in the appropriate characteristic impedance.
Depending on what you're doing, be aware of the amount of power that each attenuator can dissipate. Putting 1W into a 30dB attenuator means only 1mW comes out - the attenuator has to dissipate the rest!
