The names that you give, "lq semaphore distant", appear to be the untranslated base text names, suggesting that you do not have translation texts installed, or you are using a language for which no translation of the signals is available. In the case of the former, I recommend checking that you have installed the pakset correctly.
If you are using the Simutrans-Standard version of this pakset, it may be that the translation texts have not been updated for the improved signal objects. In any event, in simple terms, assuming that you are using Simutrans-Standard, the following naming scheme obtains:
"... distant": pre-signal;
"...junction": choose signal; and
"...stop": basic signal.
I hope that this helps.
