What can be expected to give a spectrum most closely like that of the Helium atom Lithium?

Helium has two electrons around a nucleus so you would look for an element that has two electrons more then filled shells. Lithium has 2 electrons in a filled shell and 1 electron more so it wouldn't work too well. Beryllium has 2 electrons in a filled shell and 2 electrons more so it would work pretty good. Magnesium has 2 electrons in a filled shell, 8 electrons in the next filled shell and 2 more electrons so it would also work pretty good.

Why does lithium have a higher first ionisation energy than helium?
Helium has a higher ionization energy than in lithium. Further, helium has the highest first ionization energy in all the elements in the periodic table. Lithium has an electronic configuration of [He]2s1. The outer electron is further out and experiences a lower effective nuclear charge. The 2s electron is further out from the nucleus than the 1s electrons in He. Lithium has an atomic radius of 152pm, whereas helium is calculated at 81pm. The effective nuclear charge on the helium electrons is higher than that acting on the 2s electron in Lithium. Estimates vary a little but roughly for helium it is .69 units. For Lithium the effective nuclear charge is 1.3 due to the "shielding" caused by the inner 1s electrons.
Are lithium and holmium both elements?
Lithium is an element, however "Holmium" is not you may be mistaking Holmium for Helium though
What is the element first found in the Sun's spectrum?
Helium
Does helium mean the first?
Helium is derived from the Greek for the sun, helios, as it was discovered in the spectrum of the sun
