You can say "Tud yma, boi!" (tid uh-ma boy) which is what I'd say, or if you wanna use the proper word for "boy" in Welsh then it's "bachgen" but it's less of a mouthful to say "boi", heh.
"Dee yma" is how you say "come here" in Welsh.
"Boy" in Welsh is "bachgen."
The phrase 'come in' in Welsh is "dewch i mewn".
Dewch ymlaen
Rydym yn cyfarfod yma.
you can't translate englsish phrases into welsh as you can words... so instead you could say , "byswn i'n dwlu taset ti yma" = i'd love it if you were here
ha'u ki' heni = come here ha'u ki' heni ta'ahine = come here girl ha'u ki' heni tamasi'i = come here boy foki mai = come back
Mae'n hyfryd cael bod yma.
'I am English' in Welsh is 'Dwi yn Saesneg'
To say come here girl in Spanish you would say, ven aqui, chica. You could say come here boy by saying ven aqui, chico.

"Na" is the word for "no" in Welsh.
