Could someone help me understand that what difference do the "Radar sensitive" and "Radar sensitive passive" have in wireless log for 5 GHz?

I'm trying to figure out if I can use DFS channels as the neighbours don't seem to utilise those.

I see from the log that I've gotten a DFS hit 48 hours ago (when I had it set as 100) but I was wondering that can I interpret something from certain channels being "passive" in the log?

I don't think it matters knowing... your premise is to find a DFS channel you can use, but you are actually searching for a DFS control channel you can use... the router needs to append 3 or 7 more neighboring channels to get 80 or 160MHz bandwidth... it must use more RF spectrum than just the control channel frequencies. So, looking at your list of channels, the max bandwidth you would want (80 or 160MHz) will most likely span both 'passive' and not 'passive' channels in your list. Plus, they are all marked 'sensitive'.

(Some clients may not see a DFS control channel. If you have any, you would want to use a non-DFS control channel in the band next to the DFS channels so that they can connect at 80MHz max bandwidth while a 160MHz client can still try to use an additional 80MHz bandwidth in the DFS band.)

So, given your DFS hit... you may not be able to use DFS channels reliably in your location. I can here, but I don't need it AND I have determined that my AiMesh wireless backhaul is actually slower (lower link rate) at 160MHz than it is at 80Mhz bandwidth... most likely due to the lower transmit power at 160MHz compared to 80MHz. If my wired backhaul fails, I want my wireless backhaul to turn ON and serve as fast as possible... it does at 80MHz (1000mW max Tx power), no lower power DFS band required (250mW max Tx power).
