We construct new families of non-hyperelliptic Lefschetz fibrations byapplying the daisy substitutions to the families of words $(c_1c_2 \cdotsc_{2g-1}c_{2g}{c_{2g+1}}^2c_{2g}c_{2g-1} \cdots c_2c_1)^2 = 1$, $(c_1c_2 \cdotsc_{2g}c_{2g+1})^{2g+2} = 1$, and $(c_1c_2 \cdots c_{2g-1}c_{2g})^{2(2g+1)} = 1$in the mapping class group $\Gamma_{g}$ of the closed orientable surface ofgenus $g$, and study the sections of these Lefschetz fibrations. Furthemore, weshow that the total spaces of some of these Lefschetz fibraions are irreducibleexotic $4$-manifolds, and compute their Seiberg-Witten invariants. By applyingthe knot surgery to the family of Lefschetz fibrations obtained from the word$(c_1c_2 \cdots c_{2g}c_{2g+1})^{2g+2} = 1$ via daisy substitutions, we alsoconstruct an infinite family of pairwise non-diffeomorphic irreduciblesymplectic and non-symplectic $4$-manifolds homeomorphic to $(g^2 - g +1){\mathbb{CP}}{}^{2} \# (3g^{2} - g(k-3) + 2k +3)\overline{\mathbb{CP}}{}^{2}$ for any $g \geq 3$, and $k = 2, \cdots, g+1$.
