Stations with similar name, which to choose?

Hi, I'm going to visit alpine route from Takayama. I should stop at Tateyama, but I found that there are tateyama (Chiba), tateyama (Toyama), tateyama(yamagata). Which station should I choose?

Besides, I'm going to Hakone for Mount Fuji scenery at Hakone. I will depart from Tokyo, Which station should I choose ?
Hakone - Itabashi? Hakone-Yumoto? Or Hakonegasaki?

Furthermore, I'm confuse on how to choose the destination for alpine route as well. 26 Nov I will be travelling to Tateyama, after done with alpine route attractions, I will need to go back to Takayama for another night stay, and leaving to Tokyo in the next day after visiting Hida Furukawa.

Can you advise which destination to choose for the convenient to get back to Takayama later. Should I choose Tateyama station as start point, Murudo as destination and Dentetsu Toyama as Finish point?

Dententsu as finish point can save time in the train to go back to Takayama, am I right?

Kindly advise, million thanks in advance.
